It looks and acts like a tensioner pulley but can't find one online or at the local schucks. They tried to sell me a ac clutch pulley but I don't think it acts as a clutch. Plus it's not even on the ac.

Yes that is it. What is the name of that pulley so I can ask for it at the store.

Looks like a tensioner to me. I don't know if you can replace just the pulley? Take it off and take it to the autostore, so they can see what it looks like. I did look at a couple of online partsbooks, didn't show that part. If the autostore can't get it, talk to a dealership? If that doesn't work, try a salvage yard. Sometimes them older parts can be hard to come by?

It is an idler pulley and the housing can be reused. The internal bearing can be easily obtainerd from shops that sells bearings.
